In a dihybrid cross between $AABB$ and $aabb$,the ratio of $AABB, AABb, aaBb,$ and $aabb$ in the $F_2$ generation is:

In Mendel's dihybrid cross,how many types of offspring were obtained in the $F_2$ generation that were different from the parental types?

What will be the phenotypic ratio of the offspring obtained from a cross between $Aabb$ and $Ccdd$?

$A$ diploid organism is heterozygous for $4$ loci. How many types of gametes can be produced?

The phenotypic ratio of a dihybrid cross is ....

In Mendel's experiments with garden pea,round seed shape $(RR)$ was dominant over wrinkled seeds $(rr)$,and yellow cotyledon $(YY)$ was dominant over green cotyledon $(yy)$. What are the expected phenotypes of the $F_1$ generation when a homozygous round yellow plant $(RRYY)$ is crosseded with a homozygous wrinkled green plant $(rryy)$?
